Land of the Burning Sands — Rachel Neumeier

Gereint Enseichen of Casmantium knows little and cares less about the recent war in which his king tried to use griffins and fire to wrest territory from the neighboring country of Feierabiand...but he knows that his kingdom's unexpected defeat offers him a chance to escape from his own servitude.

But now that the griffins find themselves in a position of strength, they are not inclined to forgive and the entire kingdom finds itself in deadly peril. Willing or not, Gereint will find himself caught up in a desperate struggle between the griffins and the last remaining Casmantian mage. Even the strongest gifts of making and building may not prove sufficient when the fiery wind of the griffins begins to bury the life of Casmantium beneath the burning sands . . .
